Description

TECHNICAL FIELD The present invention relates to skin treatment devices, and more particularly to galvanic skin treatment devices for providing multiple benefits using a roller head. The roller head can be used to remove hard, dry skin layers on the surface of the foot, such as the heel, sole or toes. The roller head can also be used for other skin treatments such as exfoliating, moisturizing and/or massaging the skin.

Calluses and/or areas of hard skin develop on the feet and can be caused, for example, by persistent friction or uneven pressure from ill-fitting shoes. These often occur on the heels, balls of the feet, and sides of the toes. Calluses are often unsightly, and the thicker they are, the more yellow they can appear. Over time, especially thick calluses, they can become cracked and painful. There are many known methods for reducing or eliminating calluses and calluses, including electrically operated foot rasping devices.

Known skin treatment devices provide each roller head with a single effect. The user needs to change the roller head to obtain multiple benefits from the skin treatment device.

The present invention aims to provide multiple benefits with a single roller head, thus reducing the need to switch roller heads to obtain multiple benefits.

Forms of the disclosure will be described in detail, by way of example only, with reference to the accompanying drawings, in which: FIG. Embodiments will be described below with reference to the drawings.

Figure 3 shows a roller head with radially extending flaps. FIG. 2 is a perspective view of the roller head of FIG. 1; Figure 2 shows the individual flaps of the roller head of Figure 1; It is a perspective view of a roller head.

Figure 1 shows a roller head 2 for a skin treatment device (not shown).

The roller head 2 includes a drum 6 and a polishing surface 4. The drum 6 includes a shaft 7 at both ends of the drum 6. The roller head 2 comprises one or more flaps 4 extending radially from the drum. The one or more flaps include a first surface 8 and a second surface 10.

The first surface 8 is different from the second surface 10, and the first surface 8 provides different benefits to the user compared to the second surface 10. For example, rubbing the first surface 8 against the user's skin may have different effects on the user's skin compared to rubbing the second surface 10 against the user's skin. It can bring benefits. This allows a single roller head to be used for multiple purposes.

The roller head is configured to be rotated by the skin treatment device. The skin treatment device is connected to the roller head via a shaft 7. This allows the skin treatment device to rotate the drum along its longitudinal axis. Rotation of the drum along the longitudinal axis can provide the user with benefits for his or her skin.

The one or more flaps 4 are configured to flex, such that in use the first surface 8 of the flap 4 contacts the skin as the roller head rotates in a clockwise direction and the second surface 8 of the flap 4 contacts the skin as the roller head rotates in a clockwise direction. The surface 10 of is adapted to contact the skin when the roller head rotates in a counterclockwise direction. Thus, the first surface 8 is allowed to come into contact with the user's skin in one direction, and the second surface 10 is allowed to come into contact with the user's skin in the other direction, with the flap 4 deflecting in the other direction. Since the flap 4 can be deflected in one direction, the user can obtain a first effect from the first surface 8 by rotating the roller head in different directions along the longitudinal axis. A second utility from the second surface 10 can be applied. For example, the first surface 8 contacts the user's skin when the roller head 2 rotates in a clockwise direction, and the second surface 10 is used when the roller head 2 rotates in a counterclockwise direction. come into contact with human skin.

In the example shown, the flap comprises a flexible portion where it connects to the drum 6. For example, the portion of the flap 4 proximate to the drum (ie the base of the flap) is configured to flex. The flexible portion allows the flap to flex by rotating the flap around the flexible portion. In this example, the flexible portion of the flap is relatively more flexible than the rest of the flap, e.g., the flexible portion allows the rest of the flap to move around the flexible portion. has sufficient flexibility to allow The flexible portion may have a hardness in the Shore A range, such as 20A, 30A, 40A, 50A, 60A, 70A, 80A and/or 90A Shore.

The benefits provided to the user's skin by the roller head may include removing tough skin, smoothing the skin, exfoliating, massaging, moisturizing and/or smoothing.

FIG. 2 is a perspective view of the roller head of FIG. 1. Figure 2 shows the flap in more detail. In this example, each flap has a convex shape, eg, the flap extends further radially towards the center of the roller head relative to the end of the roller head.

The tough skin is removed using a roller head with a rough surface, and the movement of the rough surface of the roller head over the skin removes the tough skin. The degree of surface roughness of the roller head will affect the rate at which tough skin is removed. For example, a roller head with a rougher surface will remove tough skin faster than a roller head with a less rough surface. The user may initially use a roller head with a rougher surface and then a roller head with a less rough surface to try to achieve optimal removal of tough skin. The examples described below may provide a convenient way for the user to achieve the desired level of removal of tough skin.

In the example shown in Figures 1 and 2, the roller head comprises one or more flaps 4, i.e. one or more first surfaces 8 having a first roughness and a second roughness. one or more second surfaces 10.

In use, the user applies the first benefit from the first surface 8 to the skin by rotating the roller head 2 in a clockwise direction. The first surface 8 of each flap contacts the user's skin in turn as the roller head 2 rotates clockwise. The first effect on the user's skin is applied when the first surface 8 of the roller contacts the user's skin. The second surface 10 of each flap 4 contacts the user's skin in turn when rotating the roller head in a counterclockwise direction, and the second effect is applied to the user's skin.

The example of FIG. 2 shows a roller with an abrasive surface on each flap. In this example, the first surface 8 has a different roughness than the second surface 10. In other examples, the roughness of the first surface 8 may be equal to the roughness of the second surface 10.

The roller head 2 can be used in conjunction with a skin treatment device having an electromechanical mechanism. The roller head 2 can be inserted into a skin treatment device and the electromechanical mechanism of the skin treatment device can be coupled to rotate the roller head. In one example, the skin treatment device comprises two arms, and the shaft 7 of the roller head is held by the two arms of the skin treatment device. The skin treatment device is configured to rotate the roller head by transmitting the rotation of the electromechanical mechanism to the roller head via the shaft 7.

In the example above, the roller head comprises nine flaps. The roller also comprises a roller head having 3 to 15 flaps, such as 4 to 14 flaps, such as 5 to 13 flaps, such as 6 to 12 flaps, such as 7 to 11 flaps, such as 8 to 10 flaps. be able to.

FIG. 3 shows a single flap 4 showing the second surface 10 in detail. Figure 3 shows the convex shape of the flap and the second surface configured to contact the skin when rotating the roller head counterclockwise.

In one example, the flap can include an additional surface located on a radially facing surface of the flap. Additional surfaces can be used to provide moisturizing, rough skin removal, smoothing, massaging and/or exfoliating benefits to the user. For example, the first surface 8 can be used to remove hard skin, the second surface 10 can be used to smooth hard skin, and the additional surface smoothes the skin. can be used for.

In the example described above, the first surface 8 provides the first utility and the second surface 10 provides the second utility. The first surface 8 may provide multiple benefits and/or the second surface may provide multiple benefits. For example, the first surface and the second surface can vary along the circumference of the roller head.

The additional portions, the first surface and the second surface, can be used to provide different benefits to the user's skin. Two or more of the additional portions, the first surface and the second surface, may also be used to provide the same benefit to the user's skin.

As shown in Figure 4, the roller head can have an indicator 16 that indicates to the user the required orientation of the roller head to achieve the first and second effects. In one example, the roller head can have arrows, color markings, letters, and/or symbols on its surface that indicate the benefits provided by rotating the roller head in a predetermined direction.

In the example described above, the first surface of each flap provides the first utility and the second surface of each flap provides the second utility. In other examples, a roller head can include a flap having a different first surface and a different second surface.

In the embodiments described above, the flap can be deflected by rotating about the flexible portion. In other examples, the entire flap is flexible and is configured to flex by flexing the entire flap. In this example, the flap may be made from a single material and have a uniform deflection. The flap may also include a hinge located at the base of the flap. This hinge allows the flap to flex by rotating about the hinge, ie, by rotating a portion of the flap about the hinge. The hinge is formed from a metal pin, for example. As an example, the flap may include multiple hinges to allow the flap to rotate about multiple points along the radial length of the flap.

In one example, the flap includes a flexible portion located at the base of the flap and at least one additional flexible portion located radially of the flap, the flap being capable of deflecting in multiple directions. .

In the above example, the flexible portion of the flap may be made from a soft rubber material, for example the flexible portion of the flap may be made from silicone, TPE, TPU, injection molded foam and/or neoprene. can. In the example described above, the less flexible portion of the flap may be made from ABS, PET, HDPE, PVC, LDPE and/or PP.

In one example, the roller head can be manufactured using 3D printing. For example, the flap may be formed using a 3D printer with a flexible portion of the flap proximate to the drum and a relatively less flexible portion of the flap from a different material than the flexible portion of the flap. Can be done. The roller head can also be formed by injection molding, molding and/or casting. The roller head can also be formed using overmolding techniques, ie two-shot molding. In this example, a portion of the flap is molded and then a flexible portion of the flap is overmolded onto the existing portion of the flap.

In the example described above, the additional surface is arranged on the radially facing surface of the flap. Additional surfaces may also be located at the radial ends of the first and second surfaces of the one or more flaps.

Further modifications and developments can be made without departing from the scope of the invention as described herein.
